The FIA seems to have argued that the tall skate fins on both sides of the cockpit will pose a risk for the driver in case of a crash – the race marshals would have a hard time assisting the driver.
The skate fins were introduced by Williams to provide an improved airflow towards the rear wing of the car. Being that the new rules for the 2009 season became more permissible in terms of the head restraint area, technical director Sam Michael proceeded in adding it with these performance-enhancing aerodynamic devices (or so it was believed).
Michael did admit, however, that Williams is considering taking them out of the picture in case it would affect car's performance in a negative way or become a threat in terms of driver's safety.
Whiting visited the F1 paddock at Barcelona the other week – during the group test – with the sole mission of checking the legality of all 2009 challengers. It was then rumored that FIA's race director was to investigate Toyota's and Williams' rear diffuser designs, as well as BMW Sauber F1.09's smaller fairing fins (also aimed to improve airflow around the car).
Williams F1 are the first team to be forced to reconsider their aerodynamic package for 2009 following Whiting's routine check last week.
